The statement in this article that ExxonMobil is the largest North American source of Group II+ should cast serious doubts about the persistant rumor that Mobil Drive Clean oil is made with Group I base oil.
Interesting. The relative prices of GrI/II/II+/III base stocks really illustrates what a rip off Gr III finished oils are. It is unlikely that differences in the additive packages can account for ~$1.10 (Gr II/II+) vs ~$4.00 (Gr III synthetic)pricing.
It is also unlikely that Mobil Drive Clean can attain its present specs without a significant amount of Gr II base.
I didn't think Drive Clean's specs were all that great except for the cleaning factor which is an attribute of group I. Maybe Exxon's a very inexpensive group II+. If Mobil isn't group I where's all that production going?
